IMPROVEMENT IN WIIIrILE-Tnnns.

TO ALL WHOM IT MAY CONCER:

Be it known that I, MELvIN C. CHAMBERLIN, of Plainview, in the county of Wabashaw, and in theState ofMin nesota, have invented certain new and useful additional improvements in WhiIie-Trees, and do hereby declare that the followinrar is a full, clear, and exact'description thereof', reference being had to t-he accompanying drawings, and to the letters of reference marked thereon.

In the annexed drawings, A represents the shafts o theninear their rear ends, and to which the whiil1e-tree is usuallyattaohed. C C represent twoA metallic. bars, made in the'form shown, and pivoted to the cross-piece'B or its upper side, and near its ends. lhe outer endsv of these bars are provided with notches similar to those upon theend of the common whi-lletree for securing the cud of the tug or. trace. ',lhe inner ends of these bars curve back of the'bar B, as seen, and are pivotedv to the outer ends of ,tliebars D and E. D and E represent two bars, made-'of metal, which lie baick oi" cross-piece B. The har D is provided on its inner end with a metallic box, 1,'open at both ends, and also with a lever, F, which is so p ivoted to it that the inner end of the lever is within the box or without, according to the position it is placed in. The bar E is provided wit-h a series of notches or teeth, as represented, and passesl into the box 'a upon bar-D. After pushing or inserting the end of bar E within the box a the, lever F is turned down, as seen, fig.' 1, and its end catches between the notches or teeth on bar E'and holds it in position. By-raising this lever` the bar maybe drawn out one or more notches or out altogether, or secured ilranydesired position. When thetraces are secured to the ends of the bars C C they have the. usual oscillating motion of 'Whittle-trees, derived from the motion of the horses shoulders. '.lhe traces' may be taken-up or let o ut by shifting the bar E in box a. A cord may be secured to' the end of lever' F, and, when driving, and a horse isv vicious or inclined to run away, it may be thrown up, vallowing bar E to draw out of bon a, aud the traces will then slip off of bars C C, and th'e horse will be detached from the vehicle.

Having thus fully described my invention, what I claim as new, and desire tosecure by Letters Patent, isi- The arrangement of the bars C C and D and E,constructed as described, and used in connection with the lever F and box a, substantially as and for the purpose herein specified.

In testimony that 1 claim the foregoing, I have hereunto set my'hand and seal this twentysixth day of November, 1866-.
